Optimizing the Design of Earth Retaining Systems

A R&D initiative led by Grid Engineers and supported by National Technical University of Athens in order to propose a resilient approach for designing earth retaining structures. The specific objectives of the research include:

  • Assessment of soil-reinforcement interaction factor as a function of transverse wires spacing and soil properties. To achieve this goal, a novel pull-out testing device was designed, manufactured and is currently being operated by Grid Engineers.
  • Comparison of the response of an optimized VSol system against other (similar) design alternatives
  • Seismic Performance of a VSol-reinforced structures: Parametric Analyses and Identification of optimum configurations
  • Guidelines and design charts
